A flange bolt has a ridge or skirt (flange) around the bolt head that distributes the clamping load when the bolt is tightened. The flange works like a washer. Flange bolts are sometimes called frame bolts.

Lag bolts have a course-pitch, threaded body and a square or hexagonal head for driving with a wrench. Lag bolts are designed to fasten wood and similar materials. They produce their own screw thread when tightened. Lag bolts are also referred to as lag screws.

Machine bolts are fully-threaded, small-caliber bolts for joining metal parts. They are screwed into pre-threaded holes and can be fitted with a nut. Machine bolts are more commonly referred to as machine screws.

Shoulder bolts have an unthreaded shank that is long in comparison to its threaded portion, which is located under the head. Shoulder bolts are used to locate one machine part to another, or as a plain bearing in places where rotary or sliding motion is required. Precision shoulder bolts are manufactured with varying diameter and shoulder-length tolerances. Shoulder bolts are also called shoulder screws or stripper bolts.

A stud bolt is a fully-threaded fastener used to hold two objects together. Stud bolts are used in conjunction with hex nuts on each end, while a stud is threaded, pressed or otherwise secured to an object on one end and a nut is used on the other.

A toggle bolt typically has an expanding wing-type nut. The wings on the nut lay flat when pushed through the opening and expand when through the opening. Typically, toggle bolts are used to attach heavy objects to gypsum wallboards.

Aluminum is a bluish, silver-white, malleable, ductile, light, trivalent, metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation. Aluminum is lighter than steel, but not as strong.

Molybdenum is a chemical element with the symbol Mo and an atomic number of 42. Molybdenum has a very high melting point (the sixth highest of any element) and is commonly used in high-strength steel alloys.

Steel is a commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. Many grades of carbon and alloy steels are used as fastener materials. Steel may require coating for protection against corrosion.

Steel can be hardened in a number of ways. Methods include quenching techniques in oil and water, and passing the steel through induction chambers. During processing, the rapid cooling of steel freezes, traps and packs the carbon atoms inside the shrunken iron crystals. The resulting steel is very hard and brittle. Hardened steel is strong, but cannot absorb much shock or impact without breaking.

Stainless steel is chemical and corrosion resistant and can have relatively high stress ratings. Many grades are used in fasteners. Often, stainless steel does not require an anti-corrosion coating; however, most stainless steels cannot be hardened to the same degree as carbon steels.

Superalloys are high-performance alloys that exhibit the following features: mechanical strength, good surface stability, resistance to corrosion and oxidation, and resistance to creep at high temperatures. Common superalloys include Hastelloy®, Inconel®, Incoloy®, and Monel®. The attributes of Hastelloy® alloys include high resistance to uniform attack and localized corrosion resistance. It also provides stress corrosion cracking resistance, and ease of welding and fabrication. Hastelloy is a registered trademark of Haynes International, Inc. Inconel® and Incoloy® (Special Metals Corporation) provide good strength and excellent resistance to oxidation and carbonization in high temperatures environments, and in many aqueous environments. These proprietary materials are used in process piping, heat exchangers, heating element sheathing and nuclear steam generator tubing. Typically, Inconel and Incoloy are used at service temperatures below 650° C (1200° F). Monel® (Special Metals Corporation) is a proprietary, high-strength alloy that offers resistance to a range of corrosive media, including seawater, hydrofluoric and sulfuric acids, and alkalis.

Titanium is a hard, lustrous, silvery element that is relatively abundant in the Earth's crust. It is valued for its lightness, strength, and corrosion resistance. Titanium is used widely in the aerospace industry and in medical products such as replacement joints. When alloyed with other metals, especially steel, titanium adds strength and oxidation resistance.

Dimensional and material standards for aircraft fasteners are developed by the Aerospace Industries Association (AIA) and/or its National Aerospace Standards Committee (NASC). All drawings and specifications have a NAS or NASM prefix. NAS is an acronym for National Aerospace Standards. NASM is an acronym for National Aerospace Standards, Metric.

The American Society of Mechanical Engineers (ASME) B18 standard specifies all ASME B18 fastener products with a single 18-digit PIN code system. Approved by the American National Standards Institute (ANSI) and adopted by the U.S. Department of Defense, the ASME B18.24 PIN system is a self-contained code that covers 788 unique B18 fastener types from 72 ASME B18 source documents. The PIN code system is fully parametric, uniform across all fastener types, and is intended as a digital alternative to the traditional plain text fastener product callout prescribed in the "Designation" or "Ordering" section of the applicable source document.

Dimensional and material standards developed by the British Standards Institution. Standards are designated with a BS prefix. The British Standards International (BSI) Kitemark indicates that products are tested regularly against the requirements of an appropriate BSI standard, and that the manufacturer's quality system is assessed at least twice a year to ensure continued quality production.

DIN is an acronym for Deutsches Institut für Normung (DIN), a German national organization for standardization. Most metric fasteners are manufactured according to DIN standards. Although DIN predates the International Standards Organizations (ISO), DIN standards are being revised to more closely match ISO standards. Ordering DIN fasteners requires three pieces of information: the DIN identifier, which defines the style of the fastener; the material (e.g., 8.8 Steel, 316 Stainless, Hastelloy C276); and the coating or plating (if any).

The International Standards Organization (ISO) is a worldwide federation of national standards organizations from over 100 countries. ISO's mission is to facilitate the international exchange of goods and services, and to foster cooperation in the spheres of intellectual, technological, and economic activity. ISO standards for metric fasteners are gaining recognition rapidly. They will probably become global standards.

Japanese Industrial Standard (JIS) is largely based on DIN; however, some standards have been modified to meet the needs of the Japanese market. Most of the fasteners used in electronic equipment manufactured in Japan comply with the JIS standard.

Fasteners meet standards developed by the Society of Automotive Engineers (SAE), a worldwide organization that establishes industry standards for the testing, measurement, and design of automobiles and their components.
